Experimental result of the periodic projection target. (a) The periodic projection target; (b) image of the object captured by the CCD; (c) the original speckle pattern captured by the CCD; (d) the imaging results of (c); (e), (g), (i), and (k) speckle patterns modulated at different polarization angles in the same ROI; (f), (h), (j), and (l) the corresponding imaging results (10,000 measurements); (m) and (o) speckle patterns at the same polarization angles in different ROIs; (n) and (p) the corresponding imaging results (10,000 measurements). The results of this experiment were all subjected to pseudocolor processing. Scale bar = 2 mm.
